NOTE: This article was originally written in December 1995. It is still accurate to compare product features. However, prices are changing weekly. Updated (Summer 96) info at bottom of the article.
The kings of removable storage, SyQuest and Iomega, have introduced affordable new entry-level removable storage solutions--the Zip from Iomega and the SyQuest EZ135. With these products arriving at a street price around $200 US for the drive, and $20 US per 100MB+ cartridge, the removable market has just become affordable to most computer users. These products debuted in the Summer of 1995. The Zip came first and with promises of low cost backup and transport, they were a fast success. SyQuest later followed with their EZ135 and slightly more capacity, at around the same price.
With the addition of the 1-gigabyte capacity of removable storage devices just introduced, this places removable products in three distinct user levels.
lower capacity, consumer home user, small business user, backup, travelers
- Iomega Zip
- SyQuest EZ135
mid-range capacity, utilizing extensive existing user-base, desktop publishing, service bureaus seeking user compatibility
My guess is that this product line (from each vendor) will be phased out gradually.
- Iomega Bernoulli (35MB to 230MB capacity cartridges)
- SyQuest (5.25 inch platters: 44, 88, 200)
- SyQuest (3.5 inch platters: 130, 270)
high capacity, high-end prepress, CAD/CAM, multimedia and video users, mass storage needed
- Iomega Jaz (1 GB) "now shipping" (still waiting?)
- SyQuest SyJET (1.3 GB) shipping 1996
At this time, the three levels are not cross-compatible within their own brands. The future may see a change to that. The EZ135 cartridge is the same cartridge as the mid-level SyQuest 3.5-inch 270MB cartridge (but you cannot use the 270s on the EZ). With the EZ135 technology, only one side of the platter is written. I predict that future versions of the EZ drives will cross-read/write across product levels (see July update at end). The Bernoulli, Zip and Jaz cartridges are three unique physical cartridges.
For this article, we focus on the two hot consumer-level products, the Zip and the EZ135. Specifications for these two products follows.

Bundled Software with EZ135...
Silverlining Lite (driver/diagnostic utility), DiskFit Direct* (backup), PowerMerge* (File synchronization), VirtualDisk Lite (cataloging with label software EasyLabels Starter), Paint Alchemy* (Photoshop plug-in), Marathon and Pathways (games).
MS-DOS & Windows:
Enhanced SyQuest Utilities for DOS & Windows, Personal Archiver (disk storage manager), PaperClip* (image & fax management), Media Wrangler* (multimedia authoring), Enhanced SyQuest install programs (including ASPI SCSI managers from most HBA suppliers and database of IDE jumper settings)
* Denotes full-function software. Many softwares here are limited but can be upgraded to full-function versions at a nominal fee. Each EZ135 drive cartridge contains both Mac and Windows-compatible software. This bundled software is available on all cartridges, not just the ones shipped in the drive box.
Each drive comes with a flyer of additional accessories available to purchase. These include carry cases and universal power adapters. It is recommended that if you intend to transport between locations regularly, buy an additional power adapter for the other location, carrying only the drive and cartridges back and forth. Note: Iomega also has 25 MB cartridges available for the Zip.
The TestI installed each drive on a Macintosh IIci system with: Daystar PowerCache 50mhz, 32MB RAM, 105MB Hard Disk, Silverlining 5.3 drivers, SCSIProbe 3.5sq, no additional external SCSI devices. During tests, the drive being tested was the only external device installed. I copied the contents of the 105 internal drive onto the two removables to simulate a backup. There were a total of 1016 files occupying 90.5MB hard disk space. I use Symantec's CopyDoubler (v 2.04) extension for copying. This lists the total throughput and read/write/verify speeds. I had no errors when performing these tests.

Pros and Cons Applicable to Both Products...(Indicated by a plus or minus sign at each item)
+ Both drives are impressively quiet.
+ Easy of installation. I plugged the equipment in and mounted the included disk without installing the software. I have always hated extra extensions and drivers that were not needed. I did install the drivers just to test them and had no problem and no incompatability.
+ Both drives have printed documentation for each platform within the package. Each instruction sheet is only an 11 by 17 inch single sheet of paper printed both sides--no lengthy manual.
- The power bricks have the electrical plug on the brick itself. Don't we have a hard enough time finding room in our surge bar for plugs, let alone large over-sized power brick plugs? Vendors: Please place the brick further down the cord than at the end. Give us a standard plug on the end of the cord. (Puuuh-leez!)
- The free cartridges that come with each drive are a bit misleading. The flyers and marketing materials boast that the drive comes with your first cartridge. You may not realize that the drive software and free bundled software come on your new "free" backup cartridge! And just where are you supposed to backup that software? Iomega calls that initial cartridge different than their others--it is called Zip Tools. Other cartridges from Iomega are named Zip Disk and have only a small marketing text file pre-installed on them. (Additional EZ135 cartridges come with the same software as the initial cartridge.)
- Because of the popularity of these products, speaking with support at the vendors may be difficult. The automated toll-free numbers (US) warn of 20 to 30 minute wait times before being able to speak with tech support. You may be better off getting support online. Each vendor has an extensive FaxBack system with many troubleshooting tech notes, especially for PC users. SyQuest's FaxBack is toll free in the US.
Specific Pros and Cons to Each Product
IOMEGA ZIP...My setup: The Zip was set to ID 5 and termination activated. The termination is built in. An on/off switch on the back sets the termination and a separate switch selects SCSI ID 5 or 6. I connected it with a 25 to 25-pin SCSI cable (included) directly to the Macintosh.
+ Very lightweight, drive and cartridge. Even with the power brick it is light. The brick itself is much lighter than the one I have with my modem. I was very impressed with the portability. Great for use with notebook computers. The power cord recesses into the side of the drive for vertical use so it does not affect stability of the drive.
+ The see-through window on the drive allows you to read the label contents while inserted. This is a definite benefit. With normal removable media, the only thing in easy view is the end label (if you labeled it!). With the Zip, you can see the entire label on the top of the cartridge while inside the drive.
+ The Zip puts itself to sleep after a period of inactivity to conserve power. It seems to wake instantaneously.
- No on/off switch. If you wish to turn the equipment off for an extended period of inactivity, you are instructed to unplug the power brick.
- Slower (when compared to the SyQuest drive)
- Upon restart, the Zip always ejected itself. I was a bit annoyed when I had to re-insert the cartridge each restart. (I restart frequently when testing new software and hardware.) The instructions with the Zip often repeat the warning that the Zip should be powered up before inserting or ejecting media. I have never had this requirement with SyQuest media and it makes me nervous as to why this instruction needs repeating. I often insert and eject media with power down on a SyQuest.
- The short cable length of the power cord annoyed me and limited my placement of the Zip on my desk top.
SYQUEST EZ135...My setup: The EZ135 was set to ID 5. I connected it with a 25 to 50-pin cable (included) and the 50-pin standard grey terminator (included) directly to the Macintosh. The included terminator was neither pass-through nor active.
+ Speed. They boast twice the speed in marketing materials, but my test did not show that much of an increase, but it was enough to make it more pleasant.
+ Larger capacity. 135MB (125.9MB formatted). More storage is always a good thing.
+ The EZ drive has twin 50-pin ports, external termination and external fully-switchable ID (0 to 6).
+ Nice SCSI ID switch. I like the recessed externally switchable ID switch. You must use a pen or something with a point to depress the up or down advancing buttons. This is a welcome change from the existing mainstay of SCSI switches. Too often, an unwary user places their hand in the back to power down and accidently hits the advance button to reset the ID, often causing the system to become confused upon restart or next power up. I really like this new switch.
- Weight. The power brick alone is extemely heavy. The power brick for the EZ weighs more than the Zip drive with its brick.
- The eject/insert mechanism is not as nice as it is on the larger SyQuest drives, likely a victim of cost cutting to keep price down. The levers and buttons seem a bit small. I suspect that men (with larger hands) could find this annoying.
Factors to consider when deciding which product to buy...Tech support and these drives tend to be in short supply as demand has far exceeded production. Your wait time to actually get product may be a factor to consider. They are in short supply in the US, so shipping schedules are likely to be bad outside the US.
How do you intend to use removable media? If you are intending it as local backup and not for exchange of files with anyone else (ever), then you could select either one and likely not go wrong. But, if you are planning to transport files to/from a collaborator, client or service provider, first find out what they use. Unless you are a highly valuable, regular client, they will likely not purchase a specific brand to match your equipment, unless you pay for it. It is critical to match what will be used by the people on the other end of your to/from transport.
Don't be the only one you know with a new technology. It helps to know others who also have the same equipment for cross-support. The vendor's tech support alone may not be enough (and how many times have we found that so in other products?). Friends and acquaintances can be contacted quickly and maybe they have already solved the problem you may just now be experiencing. Even if it cannot be solved, it may be of comfort to know that you are not nuts, someone else experienced the same odd event.
Service and support. Price? Features? Capacity? Nothing is more valuable than your time. If you bought a product at bargain basement prices and then had nothing but problems with it, where is your value? Service and support vary upon your geographical location, as well as that particular vendor's support structure. Investigate first. Ask your friends and business associates. User groups and professional trade groups may also have recommendations. Find out more about this often-overlooked "feature" before you buy. I would rather pay more to get peace of mind in my work, than save a few dollars. My time, clients and deadlines are more valuable to me in the long run.
If you need removables as places to backup, archive and transport, then either of these drives will do. I really don't think you can go wrong with either of these products. It just depends on your configuration and projected use. Speed, portability, and warranty are the primary differences in these two drives.
In June 1996, the EZ135 was reduced in price to $119 for the drive. Cartridge prices remain the same. SyQuest has also delivered another product, the EZFlyer 230 which reads and writes 135MB EZ cartridges, as well as its own new 230MB cartridges. The EZFlyer is $299 for the drive and $29 per 230MB cartridge. The EZ135 drive is due to be dropped this fall/winter from existing product lines. It has outlived it's marketing lifeline (as many computer products do). The EZFlyer takes its place.
Updated information Summer 1996
Speculation is that Iomega will release a 200MB Zip in the coming months. A $50 rebate is presently being offered on the 100MB Zip to compete with SyQuest's EZ135 price drop.
PRICE DISCLAIMER: I will no longer be responsible for prices quoted in this article. Iomega and SyQuest are treating these drives, as well as the Jaz as commodity items. Prices are dropping weekly! Call your local reseller or mail order company for the most up-to-date prices.
